UNITED STATES PATENT OFC.

PHILIP T. SHARE, OF BALTIMORE, MARYLAND.

STEERINGr-WHEEL FOR VESSELS.

Specification of Letters Patent No. 2,865, dated November 28, 1842.

To aZZ whom t may concern Be it known that I, PHILIP T. SHARE, of thecity of Baltimore and State of Maryland, haVe invented a new and usefulImproveinent on the Steering-Vheel for Ships and other Vessels; and I dohereby declare that the following, with the accompanying drawings, is afull and exact description.

My improvenientis as follows: The steering wheel a, a, a, F igure 1 issupported on i a stand Z), Z), which is bolted to the deck (as at c, 0,)&c. The wheel has a shaft (Z, on which is the driVing pinion 6,' thispinion works in the cogwheel f, f, which cogwheel is on the drum g. 72,,is another drum resting on the same shaft; a part of which is at Fig. 2.This shaft is stationary on the frame Z), Z). These drums are to movearound in opposite directions. h, moVes contrary to g, by'means of theinner cogwheels represented at Fig. 2, and as follows: j, j are twomiter wheels on the inner ends of the drums. On the shaft as at 76, isfiXed an armed projection with the miter pinions Z, Z, turning on theends of said arms. iThe pinions work into the wheels on the drunis andby the motion of the wheels a, and e, it will be seen that the drumsmove in opposite directions. The drums receive the ropes m, m, from theblocks n, n, and from the tiller 0,' the pulley blocks being fastened tothe deck. By the use of this arrangement the steering wheel is both moreready and manageable; the ropes being always tight and not subject tobecome slack, as has been the case with the usual steering apparatus.The Vessel will be goVernecl by the tiller the instant you lay hold ofthe wheel, and this is the great ad- Vantage this plan has over thecommon wheel, and is the reason the usual hand tiller has beenpreferred.

Fig. 3, represents a side View of the druins (as Fig. 2) separated,showing the cogwheels on the drum and the pinions on the arms. Thetillers in both figures refer to thel samev parts. The dotted lines Fig.3 show an inner lap of the drum from the right, so as to hide or inclosethe cogwheels.

vsuitable size to get the required motion, as

r, on the shaft (Z, Fig. '1, and s, on another shaft; the cogwheel 8workinginto a cogwheel-t, on the end of drum h, Fig. 1.

Fig. 5 shows the form of the end of the tiller, the object of which isto effect an e ual line and tension of the rope between the pulleys, asfrom n, to n, Fig. 1, and to equalize the effect of the action of theropes and drums a, a, a Vertical slots through the tiller, in whichworks back and forward the slide Z), b, which is seen detached as at c.It has a Vertical roller (Z, which runs in the Vertical slot a, to easethe running. e, e, &c., on both pieces are iron eyes to which the ropesare attached as at e, e, Fig. 1. f, is a cap to cover f, f

VVhat I claim a's my inVention and desire to secure by Letters Patent,is

The combination and arrangement of the parts, consisting of the steeringwheel and its shaft and cogwheels, and the drums and the gearing todrive them in different directions; and the construction of the tiller;all as represented in the 5 figures Operating as, and for the purpose,before described.
